TRUCK FOR WHEELED VEHICLES.

Application led January 6, 1913.

To all whom t may concern.'

Be it known that we, CLEMMA R. RANEY and Ronnu'r C. LrvnsAY, citizens or' the United States, residing at Chicago and Moline, respectively, in the countyof Cook and the county or Rock Island, respectively, and State of Illinois, have invented certain new and useful Improvements in Trucks for Wheeled Vehicles, of which the following is a full, clear, and exact specification.

Our invention relates to trucks for wheeled vehicles.

It has for its object to maintain the wheels of a truck in such relation with respect to each other during angular movement of the vehicle that the latter may be readily turned in a small space without sidewise dragging of the wheels. `We attain this object by providing improved means independent of the truck which, when the latter is turned, automatically turn the wheels in such angular relation with respect to each other that the same move through arcs of eccentric circles of different diameters.

In the accompanying drawings we have illustrated one embodiment of our invention adapted to use in connection with a grain shocker. It is to be understood, however, that the embodiment shown herein is susceptible of modification and adapted to use in other connections.

Figure l is a top plan view of the shocker trame and the transport wheels.

Fig. 2 is a side elevation ol the saine, the frame being shown to be supported on a member protruding from the harvester.

Fig. 3 is a diagrammatic view of our invention applied to a grain shocker, the latter being attached to a harvester.

In the construction shown a shocker' ame l is carried between a pair of rotatable vertical standards vmounted on a single pair of transport wheels 3. The forward end of this frame l is supported upon a rod or bar elprojecting from the side of the harvester and is so positioned with respect thereto by a band 5 and draft links 6' that it freely movable longitudinally within certain limits, but at the saine time is drawn along and moved angularly with the harvester. Inasmuch as the construction oi the shocker Specification of Letters Patent.

Serial No. 740,482.

:trame and the harvester per se forms no part of this invention, a specific description of the same is omitted.

In our improvement we mount the transport wheels 3 upon stub axles 7 projecting outwardly at right angles from the rear ends of substantially horizontally disposed normally parallel axle shanks 8. As shown 'in Fig. 2, the shanks 8 are preferably formed integral with the standards 2 and extend substantially at right angles therefrom toward the rear of the machine. In liront of the standards 2 each of the shanks S is provided with an elongated front shank 9 which is preferably formed integral therewith and bent slightly downward, as shown in Fig. 2, so that it will not engage with the lower horizontal portion of the frame 1. The free ends of these front shanks are pivotally connected to each other through a connecting link, or reach rod, l0. In the drawings we vhave illustrated the transport gear to be or' a construction adapted to use in connection with a left-hand harvester 11; that is, a harvester which cuts at the left and always moves around the grain in a counter-clockwise direction, turning toward the left about its main wheel 12. In this construction the front shank 9 of the leftb and shank 8 is made shorter than the shank 9 ou the right-hand shank 8 to such a degree that when the :trame 1 is moved angularly to the lett about a pivot on the harvester drive wheel, the right-hand wheell 3 is turned through a smaller angle by the pivoted cou- .nection 1.0 than the lett-hand wheel, so that it moves through a larger circle than the latter. Obviously, when it is desired to place our improved construction upon a right-hand harvester, it is only necessary to reverse the relative relation of the parts. It is obvious that il desired the member l() may be connected between the rear shanks, the latter, in such a construction, being made ol unequal length in the manner in which the :[ront shanks are shown in this application.

The operation of the construction shown is as follows: When the harvester l1 makes a left-hand turn, (Fig. 3) as at the end oit the field, the shocker frame is swung about in a forward direction and to the left, the'main Patented Feb. 20, 1917.

wheel 12 of the harvester' forming the axis. As the frame 1 is thus moved angularly, the wheels 3 of the shocker are automatically turned to the right toward the dotted line position shown. Due to the pivotal connection between the wheels 3 and the difference in the llengths of the front shanks 9, the right-hand wheel is automatically turned through a smaller angle than the left-hand wheel, so that, during the continued angular e,movement of the frame, it moves through the arc of a circle larger than that described by the left-hand wheel and eccentric with respect thereto. Obviously, as soon as the turn is completed and the harvester straightens out for the cutting operation upon the next stretch, the frame 1 is automatically swung forward and the wheels 3 are returned to their normal parallel relation with respect to each other. Should the turn made by the harvester be to the right instead of to the left, obviously the angular movement of the wheels would be reversed.

It is to be noted that the wheels 3 are kept in the desired angular relation with respect to each other throughout the entire angular movement of the frame, and that the off wheel is always freely rotatable about its axle so that sidewise sliding of the wheels and the consequent burying of the same in the ground is thus avoided. This results not only in reducing the wear and tear upon the truck and the machine carried thereby, but at the same time cuts down the necessary amount of power requisite to move the truck. It is further to be noted that the parts are so pivoted that a small movement of the lefthand wheel 3 is imparted directly to the right-hand wheel, and that, due to the lever arrangement employed, a minimum of effort is required to move the latter about its pivot.

While we have described one embodiment of our invention in this application, and shown the same adapted to use in one connection, it is to be understood that the construction shown herein may be modified without departing from the spirit of our invention and may be used in other constructions. y
